Sounder: Fishing Guide

Drop a pin on any water and Sounder tells you what's there, what to tie on, and when to go — then learns your patterns with every catch.

Every fishing app shows you data. Sounder tells you what to do.

Drop a pin on any water in the US — a tidal creek, the surf, a reservoir, a kelp bed — and Sounder reads it: what kind of water it is, which fish are likely there right now, the one bait to tie on, and exactly how to work it.

TODAY, AT A GLANCE The day's tide curve with your bite windows drawn on it, live water temp, wind, light, and a two-day trip planner that says when to go — not just what the weather is.

A GUIDE IN YOUR POCKET 58 species across every US region, each with real seasonal knowledge: rigs, techniques, tackle, best tides and light. Backed by live NOAA tides, marine forecasts, barometric trend, water clarity, and solunar feeding windows — and an AI briefing that talks you through the spot like a guide on the bow.

VERIFIED, NOT GUESSED Photo-verified fish observations near your spot (from iNaturalist's public research-grade data) back up the guide with what's actually been documented in that water. No people, no pins — species only.

IT LEARNS YOUR WATER Every catch you log is silently stamped with the exact conditions. Sounder mines your own history — "7 of 9 redfish came on falling tides" — and stars the upcoming windows that match how YOU actually catch. Private, on your phone, impossible to fake with crowd data.

YOURS, ACTUALLY No account required. No social feed. No ads. No selling your spots. Your log exports whenever you want it. Optional email sync if you fish from two phones.

Also in the box: full-screen nautical charts (NOAA), depth & bottom relief, live rain radar, satellite sea-surface temperature, wave forecasts, per-state regulations links, keeper-slot flags, catch photos, personal bests, and a shareable "read" card that never reveals your coordinates.

Sounder covers US waters — Atlantic, Gulf, Pacific, Great Lakes, and every pond, river, and reservoir in between.
